Behind him on the course were Luke Donald and Keegan Bradley, who played a match that went to the 18th hole. Donald is No. 1 in the world and trying to win his first major, while Bradley has won 50 percent of the majors he has played _ OK, this is only the third major for the PGA champion, and his first U.S. Open.

Donald finally pulled away by blasting out of a bunker to 4 feet for birdie on the 17th, then getting up-and-down from a far more difficult spot in the bunker right of the 18th green. Bradley had a chance to halve the match, but missed an 8-foot birdie putt.

Also on the course was Graeme McDowell, who won the last time this U.S. Open came to northern California at Pebble Beach two years ago.

The Olympic Club is hosting the U.S. Open for the fifth time, and it has delivered one surprise after another _ Jack Fleck rallying to catch Ben Hogan and beating him in a playoff; Arnold Palmer losing a seven-shot lead on the back nine and falling to Billy Casper in a playoff; Scott Simpson running off three straight birdies late in the final round to beat Tom Watson; and Lee Janzen rallying from five shots behind to beat Payne Stewart.

From what some of the players have seen, there might not be any surprises on the golf course.

They expect it to be hard.

“It’s a typical U.S. Open _ small greens, tight fairways,” Hunter Mahan said. “You’re going to have to put the ball in play. You can’t just hit it anywhere and score. This is going to be more about where your misses are than where your good shots are.”

One difference between Olympic now and in 1998, the last year it held the U.S. Open, is the par.

The 520-yard opening hole is now a par 4, while the 522-yard 17th hole has been converted to a par 5. The low score still wins, though this change could creep into a player’s psyche. The change makes the opening six holes one of the toughest stretches anywhere in golf.

“What’s unique about this year is that you’ve got the first six holes that are beyond brutal,” USGA executive director Mike Davis said. “They’re going to walk to the seventh tee and be 2 or 3 over and think, `I’ve got to catch up,’ when in reality, they don’t.”

Donald played them a couple over par on Sunday, which might actually be par for the course.

“That start of this golf course … you could be 5 over in five holes and not be that far off,” Kevin Chappell said.

The finish can be on the softer side.

The players don’t see a par 5 until No. 16, and it’s the longest hole (670 yards) in U.S. Open history. It is followed by another par 5 that can be reached in two, and then ends with a 344-yard 18th with a fairway that looks not much wider than a country road in Ireland. Even so, players could hit wedges into the green on the last five holes depending on the pin placements and conditions.

“It’s not the most intimidating U.S. Open finish ever,” McDowell said. “I’d give my left arm for a one-shot lead playing the 17th. You’d fancy your chances. It’s not like trying to close it out at Oakmont or Winged Foot, where you’re really trying to get the job done.”

But he was not suggesting it would be easy, either.

The green on the par-5 17th is the most severe at Olympic Club. Pampling’s caddie, Kevin Fasbender, tossed a ball toward the right one-third of the green and watched it trickle to the right until it ran down the slope and some 15 yards away in a collection area. As for the 18th, McDowell was on the right side of the fairway and hit his wedge slightly to the right of the flag. It caught a cypress tree and dropped down into some of the nastiest rough on the course.

“Someone will make a real mess of 18. I’m predicting that right now,” McDowell said.

Bradley was able to experience the rough on the par 5s, which was a lesson to keep the ball in the fairway, but not to lose hope when it finds the thick grass. Even in the rough, some shots might not be bad off. The PGA champion found the right rough on the 16th hole and did well to advance it some 80 yards up the fairway. That left him 300 yards for his third shot, and he opted to play well short of the green to give himself a chance.
